Spears told Ellen DeGeneres that while she can't share the big news is yet, it'll be revealed on Thursday, October 18. DeGeneres also revealed she has news of her own: Spears will share her announcement on DeGeneres' YouTube channel.

Does this mean Spears is releasing a new album? Her last album—Glory—came out in 2016, so it's about time for a new one. Plus, since ending her Las Vegas residency this year, she'll have plenty of time to continue touring. Spears isn't giving us any clues though, so we'll just have to wait until next week to find out.

Spears' news wasn't the only big thing about her Ellen appearance. The singer also reunited with her Mickey Mouse Club co-star Ryan Gosling, who dropped by the show as a guest, too. Gosling told DeGeneres that it had been a while since they had reunited, but that he fondly remembers his time in the Mickey Mouse Club, noting how "freakishly talented" Spears was since the beginning of her career. They unfortunately didn't share screen time, but DeGeneres shared a backstage picture of them on Twitter.
